Abstract: A system includes a location controller for a building, a container arranged to store items, and a device attached to the container. The device includes a first radio and a light emitting diode. The first radio emits a signal. The location controller determines a first location of the device in the building based on the signal and communicates, based on the first location of the device in the building, a first instruction to the device indicating that the device should be moved to a second location. The light emitting diode emits light of a first color in response to the first instruction.
